- If all observations are within control limits, does that guarantee that the process is random? Explain.The Watson Electric Company produces incandescent light bulbs. The following data on the number oflumens for 40-watt light bulbs were collected when the process was in control. a. Calculate control limits for an R-chart and an x-chart.b. Since these data were collected, some new employees were hired. A new sample obtained the following readings: 625, 592, 612, and 635. Is the process still in control?employees are using proper methods to rapidly cool potentially hazardous foods that are not held hot or are not for consumption within 4 hours through daily oversight of the employee's routine monitoring of food temperatures during cooling a. true b. false
- The Watson Electric Company produces incandescent light bulbs. The following data on the number of lumens for 40-watt light bulbs were collected when the process was in control. The standard deviation of the process is 15. Calculate control limits for an x-bar chart with 3-sigma limit and draw the chart. Since these data were collected, some new employees were hired. A new sample obtained the following readings: 625, 592, 612, and 650. Is the process still in control?Using the proper control chart, determine two-sigma control limits for the situation below. a. An examiner found an average of 4.9 scratches in the outer paint of each of the vehicles being made for delivery to dealers. b. Before delivery of lawn mowers to dealers, an examiner tries to start each mower and notes any that do not start on the first try. The lot size is 200 mowers, and an average of 5 did not start (2.5 percent)Can we say the process is under control by observing one subgroup out of control limit?

Is the process still in control?Which of the following is NOT true when a process is in-control select one: a. the process includes a high precentage of satisfactory results b. the process includes random variation c. All points lie within the control limits d. the process includes variation due to special or assignable causesWhen plotting a process, with the intention of monitoring trends, which of the following apply? Select one: a. An increase in the mean and a decrease in variation is desirable b. A decrease in both the mean and variation is desirable c. The optimum mean may be lower or higher than current values d. The mean is not as important as the variation
- One of the stages in the process of making denim cloth at the Southern Mills Company is to spin cotton yarn onto spindles for subsequent use in the weaving process. Occasionally the yarn breaks during the spinning process, and an operator ties it back together. Some number of breaks is considered normal; however, too many breaks may mean that the yarn is of poor quality. In order to monitor this process, the quality-control manager randomly selects a spinning machine each hour and checks the number of breaks during a 15-minute period. Following is a summary of the observations for the past 20 hours. Construct a c-chart using 3 limits for this process and indicate if the process was out of control at any time.Waiting time (minute) at a Tim Horton is monitored using sample mean and range control charts. Six samples of n = 10 observations have been obtained and the sample means and ranges computed (in minutes): Determine the upper and lower limits for sample mean and range control charts. Is the process in control? Draw appropriate control chart (s).Which of the following is NOT usually part of a control chart a. Centre line b. Lower control limit c. Out of control line d. Upper control limit
